    Samples don't work [SOLVED]

    Paccone

      Hi I can't get any sample binary work, all them report errors.

      I set the environment variables as:

       

      export ATISTREAMSDKROOT=/home/davide/Download/ati-stream-sdk-v2.1-lnx32/

      export ATISTREAMSDKSAMPLESROOT=/home/davide/Download/ati-stream-sdk-v2.1-lnx32/

      export LD_LIBRARY_PATH=$ATISTREAMSDKROOT/lib/x86:$LD_LIBRARY_PATH



      then extract the "icd-registration.tgz" in the sdk root and link it to /usr/lib/OpenCL/vendors/libatiocl32.so so that I have:

       

      ls -l /usr/lib/OpenCL/vendors/

      lrwxrwxrwx 1 root root 71 Jul 20 17:42 libatiocl32.so -> /home/davide/Downloads/ati-stream-sdk-v2.1-lnx32/lib/x86/libatiocl32.so



      Building the samples goes fine without errors (some warnings anyway):

       

      /samples/opencl$ make


      so samples shuld now be ready, but I get errors such as:

      (Binary and associated error; other regular output suppressed)

       

      Template -> Error: Getting Platforms. (clGetPlatformsIDs)

      HelloCL -> Platform::get() failed (-1001)

      SimpleImage -> Error: clGetPlatformIDs failed. Error code : unknown error code

      FFT -> Error: clGetPlatformIDs failed. Error code : unknown error code

      no one works.

      I run Debian testing on intel cpu / gpu without discrete card.

      Since Debian's not supportet, I tried it on Ubuntu 9.04, with the same exact results.

      Thanks replying!

          nou

          on ubuntu you may try my packages. on debian it should work too. maybe just set manualy $ATISTREAMSDKROOT=/usr/local

              Tryed on ubuntu 9.04!

              installed all 3 of your first post (at Ubuntu packages with ATI Stream SDK ) and for the samples the end is that of post #4 ..

              At least this time the ICD seems set properly ;-)

              So I don know!!

              What else to get hands on opencl !

              PS ubuntu is from a virtual machine ran by the debian host

                • Samples don't work
                  nou

                  CL_DEVICE_FOUND is because it try create context from GPU device. run with --device cpu

                  HelloCL is CPU by default so there is another problem as it seems that it can not found clc and llc in $ATISTREAMSDKROOT/bin/x86/

                      Actually ATISTREAMSDKROOT was set wrong:

                      /home/davide/Download/ati-stream-sdk-v2.1-lnx32 instead of

                      /home/davide/Downloads/ati-stream-sdk-v2.1-lnx32 !!

                      So you were right it couldn't find clc and llc

                      and it works!

                       

                      but what about the link in /usr/lib/OpenCL thowards libatiocl32.so ?

                      I made it based on forum solutions about similar problems but omkaranathan says it's superfluous

                      Thank you!

                  You are doing incorrect ICD registration.

                  Please read Release Notes and Installation Notes for details.

                  To register ICD, you just have to copy the icd-registration.tgz file to root folder(/) and extract it. Thats it. No linking to any library.

                      Woow I thought "root" was the sdk root !

                      Ok so I did it and.. something changed but still errors running the samples!

                      I set the vars as in my post #1, then recompile the samples giving "make" in <sdk-root>/samples/opencl.

                      Since there all works fine. But when I launch the binaries I get some errors, anyway different from the previous:

                      ./Template

                      and so on.

                      I didn't do absolutely nothing for the sdk except what I wrote here.
